Moves moisture away from your body and helps it evaporate to keep you cool when it’s hot out and warm when it’s cold out

Made with activated carbon from coconut shells

37.5 technology is permanent and won’t wash out or degrade

The 37.5™ advantage.
When you’re trying to sleep, room temperature is important…but it’s the personal microclimate created within your bedding that really matters. As your body sweats throughout the night, traditional bedding is unable to deal with the excess moisture and heat. But bedding made with 37.5 technology helps your body better manage moisture vapor and heat to maintain an optimum comfort zone, allowing you to sleep better and longer.

How 37.5 technology works.
Naturally derived activated minerals are permanently embedded into 37.5 fibers to capture and remove moisture vapor, helping to keep your personal microclimate just the way you like it. To start, 37.5 microparticles have high surface area and a natural attraction for moisture, which combine to effectively pull humidity and moisture away from your body. Then, the microparticles selectively absorb body energy and use it to speed up the evaporation of the captured moisture. The result is that you stay perfectly comfortable all night long—no matter what the temperature around you is!
